keyctl:tldr:0ad51
The command "keyctl read ${key_name}" is used to read the value of a specific key from the kernel keyring. Here's a breakdown of the command:
-
"keyctl": It is a command-line utility in Linux used to manage and manipulate the kernel's key management facility. It provides various operations like creating, manipulating, and reading keys from the kernel keyring.
-
"read": This is the specific action or operation that we want to perform on the key using keyctl. In this case, we want to read the value of the key.
-
"${key_name}": This is a placeholder for the actual name or identifier of the key we want to read. When using the command, the placeholder should be replaced with the correct key name.
For example, if we have a key named "my_secret_key" in the keyring, we can use the command "keyctl read my_secret_key" to read its value. The command will retrieve the value associated with the specified key from the kernel keyring and display it on the console.
